After attaining me no cycle of birth and death.

idam jnanam upasritya,mama,sadharmyam agatah,

sarge pi no pajayante,paralaye na vyathanti ca.--2

By attaining the disincentive knowledge and complete realization of me exempts the being of rebirth since he has no fear of repeated birth at the time of creation and dissolution of the universe.
After knowing the juana[knowledge]sages not ordinary human becomes self realized and they never born in the time of creation and never disturbed at the time of dissolution.according to Hindu scriptures there are two times,one is beginning of creatures it is called as'utpati'and second is dissolution it is called as 'paralha'.in the time of 'parlaha' every thing finishes.creatures reborn at the time of creation.'utpathi'.in the time of dissolution every creature loses its physical form but not its subtle form.it remains as a blue print of the body.at the time of creation it reborn.as seeds of grass reborn on next season.But self realized souls are one with the universe self[God].It is like a stream which dissolves with the ocean.
